Which of the following are the best security controls for controlling on-premises access? (Choose two.)

Swipe cards and biometric scanners are the best security controls for on-premises access because they provide strong authentication for physical entry. Swipe cards (like proximity cards or smart cards) offer a tangible credential that can be revoked or tracked. Biometric scanners (fingerprint, iris, facial recognition) offer a high level of assurance by verifying unique biological characteristics, making them difficult to forge or share. Picture IDs are identification, not authentication; they confirm identity but don't control access directly. Phone authentication applications are primarily for digital access, not physical entry. Cameras provide surveillance and evidence but don't control access. Memorable questions are a form of knowledge-based authentication, typically used for digital systems, not physical access control.
